In-depth safety analysis
This extension asks for permissions like scripting and activeTab, which allow it to modify page appearance and read content on the websites you visit. This is expected for a measurement and inspection tool, because it needs to overlay rulers, guides, and pixel grids onto the current page and read element dimensions. The sidePanel permission lets it open a dedicated panel in your browser, while storage simply saves your preferences locally. The declared data collection includes personally identifiable information, user activity, and website content, which a careful user should note goes beyond just technical measurements.
For any general browser extension that can read and alter webpage content, a typical safety consideration is that it operates with broad visibility across your browsing sessions. A user should ensure such tools come from a publisher they trust, as overly broad data collection could be used to profile behavior or access sensitive information displayed on pages. It is also wise to verify that the extension's declared privacy practices align with your comfort level regarding data handling.
The fact sheet shows the strongest dimension is Maintenance & Ownership, indicating the extension is actively updated and well-maintained. The weakest dimension is Publisher & Identity, which suggests there is limited public documentation or verification of the developer behind screen-ruler.com, making their track record less transparent than ideal for a tool with this access.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
